Appendix C. Troubleshooting Tips
Appendix C.1. Debugging a LonWorks connection: Hints and tips
To test connections, set the configuration tool into a mode that will display service requests, and then
push the button on the FieldServer. A request should appear.
In order for variables to appear as outputs, they need to be declared as write variables in the FieldServer.
Declaring the Map Descriptor functions as WRBC, or WRBX can do this. See Section 5.1.2 for more
information.
If the domain and Subnet ID are defined in the configuration file of the FieldServer, these values will be
used when power is cycled to the FieldServer. If the values set here are different to what the Network
Manager has set up for the FieldServer for clients using implicit addressing, the FieldServer will stop
communicating. In this case, change these settings or remove them from the configuration file
completely and recommission the FieldServer.
